Java Error and Selenium Stale Element

Question

I continue to encounter a Stale Element bug in Selenium. From what I investigated, this error occurs when you navigate from a page or an element has been resized. I continue to encounter this error when I look through a list of web elements to try to determine one of them by value. It always fails in the if statement when I try to compare the name. Does anyone know what my problem is? On a larger question, is there a good fix for stale element error? All I saw on the Internet was to catch a mistake and skip it again. Is there a better way than this?

    int attempts = 0;
    while(attempts < 2){
    try{
    java.util.List<WebElement> elements = driver.findElements(By.tagName("span"));
    for(WebElement element: elements){
        if(element.getText().equals(elementName)){
          return element;
        }
    }
    }catch (org.openqa.selenium.StaleElementReferenceException e){
                e.printStackTrace();
    }
        attempts++;
    }
    return null;

, visibilityOfElementLocated, :

the function returns neither null nor false,

visibilityOfElementLocated

  /**
   * An expectation for checking that an element is present on the DOM of a page
   * and visible. Visibility means that the element is not only displayed but
   * also has a height and width that is greater than 0.
   *
   * @param locator used to find the element
   * @return the WebElement once it is located and visible
   */
  public static ExpectedCondition<WebElement> visibilityOfElementLocated(
      final By locator) {
    return new ExpectedCondition<WebElement>() {
      @Override
      public WebElement apply(WebDriver driver) {
        try {
          return elementIfVisible(findElement(locator, driver));
        } catch (StaleElementReferenceException e) {
          return null;
        }
      }

      @Override
      public String toString() {
        return "visibility of element located by " + locator;
      }
